Abstract

PURPOSE:To reduce man-hours on manufacture by winding a tape not impregnated with a resin on each coil, using a material having a large permeability for an impregnating resin as a spacer and unifying these coils and spacers and impregnating them with the resin when a plurality of the coils are set up on the same core or the outer circumference of a bobbin through the spacers. CONSTITUTION:A plurality of the white coils 8, which are not impregnated with the resin and left as they are brought to a taping state, are fitted and arranged on the ouer circumference of an oblong core 7 in which a large number of thin plates 6 are laminated while members to be impregnated as the spacers are interposed among each coil, and both external ends are clamped and fixed by frames 10 under the state. A material in which polyamide paper and glass fiber cloth are laminated and compressed alternately is used as the member 9 at that time, and air permeability and resin impregnating capability are improved. They are impregnated integrally with a synthetic resin, and the reactor, dielectric resistance thereof is large and an insulation thereto does not degrade, is obtained by only once impregnation.

Description

[Detailed Description of the Invention] (Technical Field of the Invention) This invention relates to a method for disposing a plurality of coils, each of which is insulated to the ground, on the outer periphery of an iron knob or bobbin made of laminated thin plates, with spacers interposed between them. The present invention relates to a reactor device having a T configuration.

[Background technology of the invention]

As shown in FIGS. 1 to 3, the above-mentioned acdle device is generally made up of a large number of laminated thin plates 1.Several TQs are made by individually impregnating and molding a synthetic resin on the outer periphery of a horizontally long iron core 2. The coils 3... are inserted and arranged [7], and the coils 3... are inserted between each other.
In order to increase the cooling effect of ..., spacers 4 made of molded F'RP bamboo are interposed, and each coil 3 and spacer 4 are connected to the inner and outer sides. The coils 3 and 4 are fixed from the ends by frames 5 and 5, and in this state, the entire coils 3 and spacers 4 are impregnated with synthetic resin and molded.

[Problems with background technology]

By the way, in the conventional glue accelerator device having the above-mentioned configuration, when manufacturing the same, molding is performed by impregnating each coil 3 with fat, and after assembly, molding is performed by impregnating the entire body with synthetic resin. Therefore, there was a problem that the work was troublesome and required a lot of time, leading to a significant increase in costs.

Therefore, each coil 3... is arranged together with a spacer 4... on the outer periphery of the twisted iron core 2 which is not impregnated with resin, and is tightened and fixed with the frames 5, 5 at both outer ends. We considered reducing the number of manufacturing steps by tA'+ by integrally molding the whole body by impregnating it with synthetic resin. However, conventionally, a synthetic resin molded product such as FRP was used as the spacer 4, and ...In order to prevent the vibration generated in the coil 3, the frames 5, 5 at the inner and outer ends of the 1411 are tightened so that a considerable amount of pressure is applied to the contact surface A with the coil 3, so it is tightened only once after assembly. Even when the entire synthetic resin is impregnated, the following functional level defects occur even though the resin is not properly impregnated. Since the synthetic resin does not penetrate into the contact surface between the trench recoil 3 and the spacer 4, the penetration causes a decrease in MEG value, an increase in tangent delta, poor withstand voltage, and accelerated insulation deterioration. This will cause a lot of trouble.

[Purpose of the invention]

This invention was made in view of the above circumstances, and by simply impregnating the entire body with synthetic resin in the assembled state, it is possible to create a reliable mold without any inconvenience in terms of functional soil or characteristics, and to reduce the number of manufacturing steps. Okiichi J aims to provide a reactor device 1 that can reduce costs and make the work easier.

[Summary of the invention]

In this invention, each coil is disposed in a taped, unimpregnated state on the outer periphery of an iron core or a bottle, and
Between them, there is a spacer between the impregnated resin and a large impregnated part, and the coil and the impregnated part are >1tY.
4: It has a structure in which J is integrally impregnated with synthetic LD resin and molded, and the manufacturing process is reduced by using materials such as polyamide paper and glass fiber cloth laminated and compressed together, and the spacer Even if considerable pressure is applied to the surface in contact with the coil, the resin can be impregnated well, resulting in a strong structure, and is a low-cost, high-quality glue accelerator device that does not cause any inconvenience in terms of its characteristics. be.

[Embodiments of the invention]

J:JAn embodiment of the present invention will be explained below with reference to FIGS. 4 to 6. First, as shown in the diagram, this realtor device is
A large number of plates 6 are laminated and a plurality of one-year-old white coils 8 which are not individually impregnated with resin and are taped are inserted and arranged around the outer periphery of a horizontally long core 7, and each of the coils 8.
